Can landlords get ECO4 grants for rental properties?

Yes, but eligibility is not automatic. The private rented property generally needs an EPC rating of E, F or G, and the tenant's income or benefit status usually determines whether the household qualifies. ECO4 Flex, a council referral route, may cover tenants who do not receive a qualifying benefit but meet local low-income criteria.

Does the Boiler Upgrade Scheme apply to landlords?

Landlords who own eligible properties in England or Wales can apply through an MCS-certified installer. The grant is £7,500 for an air-to-water or ground-source heat pump, or £9,000 if replacing oil or LPG in an off-gas-grid home (until March 2027). Social housing and most new builds are excluded.

Do I need to insulate before applying for BUS?

No. BUS removed the requirement to complete outstanding loft or cavity insulation recommendations in May 2024. Insulating first still makes sense because it reduces heat demand and improves heat pump performance, but it is no longer a grant eligibility condition.

What is the current minimum EPC for renting?

Generally EPC E in England and Wales, unless a valid exemption applies.

Is the Warm Homes Local Grant available to landlords?

Landlords are not automatically excluded, but a landlord contribution may be required. The grant covers private homes in England rated EPC D to G, and household income is usually at most £36,000. A national application portal exists on GOV.UK, and delivery funding runs to March 2028.

Current MEES Rules and What Is Changing

Private rented homes in England and Wales generally need EPC E unless a valid exemption applies. The current Minimum Energy Efficiency Standards (MEES) carry a maximum penalty of £5,000 per property. The improvement cost cap is £3,500 including VAT; exemption conditions and evidence still apply (GOV.UK MEES guidance).

The government response sets out a future EPC C equivalent standard for all tenancies by 1 October 2030, with new metrics and a £10,000 cost cap (2025 consultation). This is future policy, not current law. No 2028 new-tenancy deadline exists in legislation. Plan for the announced future direction while checking the legislation that applies when the work is commissioned.

An EPC rates a property's fabric and heating system on a scale from A (most energy-efficient) to G (least). The rating does not predict actual monthly bills, which depend on occupancy, fuel use and tariffs (GOV.UK EPCs). Improving the rating typically means insulating the building envelope, upgrading heating or both.

Which Grants Can Landlords Apply For?

Three main funding routes are open to landlords in England as of September 2026.

ECO4 (ending 31 December 2026)

The Energy Company Obligation requires large energy suppliers to fund energy-efficiency measures in eligible homes. ECO4 runs until 31 December 2026 (Ofgem ECO4 guidance). Landlords can benefit, but eligibility is not automatic. Key conditions include:

The property's EPC band, the tenant's circumstances and the specific measure all matter.
For private rented homes, GOV.UK specifies EPC E, F or G as the qualifying bands (GOV.UK ECO).
ECO4 Flex is a council referral route for households that do not receive a qualifying benefit but meet local vulnerability or low-income criteria. It is not guaranteed funding.
There is no fixed entitlement based on boiler age alone, and ECO4 does not promise a free boiler to every benefit claimant.

Measures typically funded through ECO4 for rental properties include loft insulation, cavity wall insulation, solid wall insulation and, in some cases, heating system replacements.

Boiler Upgrade Scheme (BUS)

The BUS provides upfront grants towards low-carbon heating in England and Wales. Funding is confirmed through fiscal year 2029/30 under the Warm Homes Plan (BUS extension). Current approved grant values are:

£7,500 for an air-to-water or ground-source heat pump
£9,000 for those types replacing oil or LPG heating in off-gas-grid properties (available until March 2027) (BUS grant values)
£5,000 for biomass boilers
£2,500 for air-to-air heat pumps

Fossil-fuel hybrid systems do not qualify as the new installation. Most new-build properties and social housing are excluded. The property owner applies through an MCS-certified installer, and the installation must be commissioned within 120 days of applying (BUS eligibility). BUS no longer requires outstanding loft or cavity insulation recommendations to be completed before applying, though insulating first remains sensible to reduce heat demand.

A landlord replacing an ageing gas boiler with an air-source heat pump could receive £7,500 off the installation cost. The remaining balance depends on the property, system design and installer pricing.

Warm Homes Local Grant

This England-only grant targets private homes rated EPC D to G. Household income is usually at most £36,000, though qualifying benefits or postcodes can provide alternative routes. A national application portal exists at GOV.UK. National eligibility rules apply alongside local delivery and funding decisions.

Landlords are not automatically excluded, but a landlord contribution may be required. Council surveys and available local funding determine which improvements are offered. Delivery funding runs to March 2028 (budget allocation). Availability varies by area, so applying early is sensible.

Check possible funding routes for your rental property. Installers and councils confirm final eligibility.

What Work Do EPC Grants Typically Cover?

Grant-funded measures focus on the changes that shift an EPC band most cost-effectively.

Insulation is usually the first priority. Loft insulation to the recommended 270 mm of mineral wool can last around 40 years if correctly installed (Energy Saving Trust). Cavity wall and solid wall insulation are also commonly funded through ECO4 and the Warm Homes Local Grant. For more detail, see our cavity wall insulation guide.

Heating upgrades may include replacing an old boiler or installing a heat pump. Under BUS, the grant covers part of the heat pump cost. Under ECO4, a boiler replacement may be funded where the existing system is inefficient and the household meets eligibility criteria. There is no universal rule that any boiler over a certain age qualifies.

Other measures depend on the scheme and property assessment. Ask the supplier or council which specific improvements it will fund. Qualifying installed energy-saving materials currently attract zero VAT through 31 March 2027, after which the rate is scheduled to rise to 5% (HMRC guidance).

Illustrative Cost Example for a Landlord

The following is a hypothetical budgeting example, not a market quote. Actual costs depend on property type, location and installer.

Item	Assumed gross cost	Assumed grant	Landlord pays
Loft insulation (3-bed semi, topped up to 270 mm)	£600	£600 (ECO4, if eligible)	£0
Cavity wall insulation	£1,500	£1,500 (ECO4, if eligible)	£0
Air-source heat pump	£12,000	£7,500 (BUS)	£4,500
Total	£14,100	£9,600	£4,500

Assumptions: The loft and cavity costs are illustrative round figures. The heat pump gross cost assumes a mid-range system for a typical semi-detached property. ECO4 funding for insulation assumes the tenant qualifies and the supplier accepts the referral. BUS grant is the confirmed £7,500 for an air-to-water heat pump on a mains-gas property. No VAT is included because installed energy-saving materials currently qualify for zero VAT. These figures are not quotes.

This example does not promise any EPC band improvement. Ask the assessor to model the proposed measures; future compliance will depend on the final rules and metrics.

How to Check If Your Rental Property Qualifies

Eligibility depends on several overlapping factors.

Step 1: Get a current EPC. If your certificate is more than ten years old or the property has changed, commission a new assessment. The EPC band determines which schemes apply. For private rented homes, ECO4 requires EPC E, F or G. The Warm Homes Local Grant covers EPC D to G. BUS no longer requires a valid EPC for applications properly made from 28 April 2026. If a valid EPC exists, the installer must provide its number, according to Ofgem installer guidance.

Step 2: Understand your tenant's circumstances. ECO4 and ECO4 Flex eligibility often depends on the tenant receiving certain means-tested benefits or meeting local low-income criteria. Child Tax Credit and Working Tax Credit ended on 5 April 2025 and are no longer qualifying benefits. Universal Credit, Pension Credit and other current means-tested benefits may qualify. Check the latest GOV.UK ECO guidance for the current list.

Step 3: Contact an MCS installer for BUS. The installer applies on your behalf. You do not apply directly to Ofgem. Ensure the installer is MCS-certified for the technology you want.

Step 4: Apply to the Warm Homes Local Grant through the national portal if your property is in England, rated D to G, and the household income or benefit criteria are met.

Our eligibility checker can indicate which routes may be open to you, though final decisions rest with installers, energy suppliers and local councils.

What If Your Property Is in Scotland or Wales?

BUS covers England and Wales. ECO4 operates across Great Britain. The Warm Homes Local Grant is England only. Scotland has separate support programmes with their own tenure restrictions; do not assume an owner-occupier offer is open to landlords. Exclusion from one English scheme does not mean no funding exists elsewhere. See our Scotland energy grants guide for details.

Planning Ahead: Exemptions and the Cost Cap

An expensive quote alone does not establish an exemption. Check the current guidance for the relevant exemption category, required improvements, evidence and registration process. The £3,500 cap includes VAT, and third-party funding can affect the calculation. Future policy uses a £10,000 cap and new EPC metrics, so current improvements should be planned with an assessor rather than assuming automatic future compliance. For a full breakdown of exemption rules, see our EPC exemption guide.
